Vortex Enclosed Solar Micro Red Dot Defender-ST 3 MOA

Meet the Defender-ST — a fast, precise red dot sight in a rugged enclosed housing. It gives you quick target acquisition and reliable accuracy. The 3 MOA dot with a 32 MOA circle balances precision and speed. It’s designed for pistols with a DeltaPoint® Pro footprint, but you can also use it on rifles or as a co-witness sight above a scope.

Key features

• 3 MOA dot + 32 MOA circle for both precision and fast aiming
• DeltaPoint® Pro footprint — fits many pistols and mounting plates out of the box
• Enclosed housing — keeps rain, dust and mud out for a clear view
• 12 brightness settings: 10 for daylight and 2 compatible with night-vision
• Built-in solar cell that can extend battery life up to 3×

Seamless pistol integration

Thanks to the DeltaPoint® Pro footprint, the Defender-ST mounts directly to compatible pistols with no extra mods. The low mount height gives you a natural sight picture. You’ll pick up targets quickly and stay comfortable while aiming.

Reliable in the field

The enclosed housing keeps the reticle clear in bad weather. Rain, dust or mud won’t obscure the red dot. That makes this sight a solid choice for heavy outdoor use or any situation where reliability matters.

Built tough

The Defender-ST is made for hard use. It stands up to shocks, drops and rough handling. Lenses have a protective coating that resists scratches, oil and dirt. You get a clear view when action heats up.

Easy visibility, day and night

Tune the reticle with 12 brightness levels. Use the 10 daylight settings for clear visibility in bright conditions. Switch to the 2 night-vision settings for low-light work. The sight stays sharp and usable no matter the light.

Long battery life

The CR2032 battery runs efficiently and the solar cell helps extend runtime up to three times. An auto-off feature prevents wasted power. The sight is parallax-free and offers unlimited eye relief for a reliable aiming image from any position.
